"I was very pleased working with Will Lohrman from the Greenberg Law Firm in Naperville. We had a case that went to Court and we were up against a big law firm from Chicago. Will was very diligent in working with me on the facts of the case, ensuring that we positioned the case effectively with the Judge, with whom he was extremely professional as he was with the other party’s counsel. He presented my case extremely well when cross-examining the other party, which showed with the results. And YES, we won!”
